That's an interesting approach. I do not think that it will work in all cases. If you poke around at the logic for rendering text in TextView, you'll find a bunch of baked-in class references (e.g., getUrls() only uses UrlSpan, spell-check logic relies on SuggestionSpan), meaning that creating your own equivalents would be at least partially ignored by the rendering code. I'm glad to hear that this works at least for foreground colors, though.
